IMPROVEMENT iN HORSE-POWER.

TO ALL 'WI-IOMVIT MAY CONCERN:

- Be it known that vI, THOMAS WILTSE, Jr., of Panama, in the county of Chautauqua, and State of New York, havo invented a new and ,improved Horse-Power; and I do hereby declaro that the following` is a full, clear, and exact description thereof, which will enable others skilled in the art to rnakeI and use thc same, reference being had to the accompanying drawings, forming part of this specification.

Figurel is a vertical section of my improved machine, taken through the line a: fr, iig. 2. Figure 2 ,is a top or plan view of the same,"part of the frame being broken away to show the construction. Similar letters of reference indicate corresponding parts: My invention has for its object to furnish an improved horse-power, designed especially for operating a drag-saw, but equally applicable for other uses, andlwhich shall he simple in construction, durable, and effective in' operation; and it consists in the combination, of the drive-wheel, vertical-shaftA pinion-wheel, horizontal shaft, vpulley-band, and crank-pulley with'each other, and in the combination of a bridge or spout with the frame 'and crank-pit'man of the machine, the whole being ccnstructedand arranged as hereinafter more fully described.

A is the drive-wheel ofthe machine, .which is set in a horizontal position, and has cogs or teeth a formed upon-the under side of its rim, which said teeth are-so formed as te point toA one side of the centre of the wheel A, as shown'lin dotted lines in fig'. 2. The lower end ofthe shaft B -of the wheel A works in a socket formed in the central sill of thoframe' C, and its upper end passes upqthrough the central top cross-bar of said frame,I

' and hasthelev'er or sweep D attached toit', to the outer end of which the horses are attached. E is a shaft,

passing horizontally across the central part of Vthe machine, at one side of the vertical shaft B, and revolving in .bearings in the fratrie C. To one end of the shaft E is attached a pinion-wheel, the teeth of which mesh into the teeth of the driving-wheel To the other end of the shaft E within the frame AC, i-s attached a bandpulley, G. -H is the'bandor belt which passes around the pulley Ganl around the pulley I, the journals of which revolve in bearings inthe frame C, and to the outer end of vone of which journals is attached the erankwheel or pulley J, to which is pivoted the en'd of the pitman K, by which n iotion is communicated to the slidingsaw pitrnan, ,or to other machinery to be driven bythe power. L is a bridge or box, attached to the side of the iframe C, to receive, guide, andi-protect the said sliding Pitman.

By this construction and arrangement of they bridge L, the horses attached to the sweep D will cross the suid'bridge obliquely, so that. they will not both cross the said bridge at exactly the same time, as they de in other powers. This does away -with the irregular-motion caused by tho slight hesitation of .the horses in stepping over thc'said bridge, and keeps the machine always moving steadily and with uniformvelo'city.

Irclaim as new, and'desire to secure by Letters Patent The combination of the driving-wheel A, having loblique teeth a', formed as described, upon the under I side Aof its rim, the vertical shaft B, horizontal shaft pinion-wheel F, band-pulley G, band or belt H, pulley I, and crank-pulley or wheel J, with each other and with the fratrie C, 'the sliding pitman-box or bridge L, the

p frame C, and'crank-pitman K,substantiallyin,the Vmanner herein shown and described, and for the purpose set forth. A THOMAS WILTSE, JR.'
